cedar to be the tree for vivian brown in san francisco. >> beautiful. thank you all for coming. >> all right. like the mayor said, this is a california tree. the tree bark was used for making medicine for people with stomach aches. it's also been used as a wind break and been used in many many parks. tree comes from the cypress family and the botanical name. i'm happy we are adding such a tree to san francisco and to honor the vivian brown sisters. now like we've done in many of our events, it's always an honor to introduce the supervisor of the district and like he said, we are very familiar with this piece of land. this land has had many trees that act as a buffer to the neighborhood and the neighborhood appreciates it but we are still trying to figure out who is the legal owner of it, but in that process, dpw and the neighbors always join and the one thing we do know is we need to take care of the trees and we do that with that, i introduce the supervisor norman yee. >> thank you, i'm just one of many san franciscans celebrating this day, arbor okay
